Harmful chemicals in building materials significantly degrade indoor environmental quality by releasing toxic substances into the air, which can lead to serious health risks for occupants.12
In the context of green architecture, a primary goal is to utilize materials that do not emit toxic gases, as indoor air quality is a critical factor in how individuals experience and feel within a space. When buildings are constructed with materials containing harmful chemicals, the following issues often occur:2
- Off-gassing: Building products such as particleboard and plywood frequently release formaldehyde, a volatile organic compound (VOC) that accumulates in indoor air.1
- Accumulation of Pollutants: Efforts to improve energy efficiency by lowering air-exchange rates can inadvertently trap these chemical contaminants indoors, increasing occupant exposure.1
- Toxic Exposure: Many conventional materials may contain hazardous substances like lead, mercury, or other heavy metals, which are known to cause neurological damage, organ failure, and carcinogenic effects.3
Green design prioritizes the use of nonpolluting, durable, and renewable materials to ensure that the indoor environment remains safe and healthy.2
